Abstract In this study, we investigate the driving forces behind the changes in residential energy consumption (REC) in China’s urban and rural areas over the 2001–2012 period. Based on the logarithmic mean Divisia index method, the REC changes are decomposed into seven driving forces, which are climate change, energy price, energy expenditure mix, energy cost share (in total expenditure), expenditure share (in income), per capita income and population effects. According to the results, climate effect due to increasing days with abnormal temperature, energy cost share effect characterized by more expenditure to be paid for energy use, income effect describing constant income growth in the residential sector definitely increase REC in both urban and rural areas. In contrast, energy prices and energy expenditure mix effects negatively contribute to the REC increase, respectively because of the increase in energy prices and the transition from the low-priced energy to high-priced energy. Expenditure share and population effects play opposite roles in urban and rural areas, and the reasons and implications are analysed in depth.

Current economic instruments aimed at climate change mitigation focus mainly on CO(2) emissions, but efficient climate mitigation needs to focus on other greenhouse gases as well as CO(2). This study investigates the distributional effects of climate change taxes on households belonging to different income and lifestyle groups; and it compares the effects of a CO(2) tax with a multiple GHG tax in the UK in terms of cost efficiency and distributional effects. Results show that a multi GHG tax is more efficient than a CO(2) tax due to lower marginal abatement costs, and that both taxes are regressive, with lower income households paying a relatively larger share of their income for the taxes than higher income households. A shift from a CO(2) tax to a GHG tax will reduce and shift the tax burden between consumption categories such as from energy-intensive products to food products. Consumers have different abilities to respond to the tax and change their behavior due to their own socio-economic attributes as well as the physical environment such as the age of the housing stock, location, and the availability of infrastructure. The housing-related carbon emissions are the largest component of the CO(2) tax payments for low income groups and arguments could be made for compensation of income losses and reduction of fuel poverty through further government intervention.

This empirical paper tests for trade-facilitated spillovers in the convergence of energy productivity across 16 European Union (EU) countries from 1995 to 2005. One might anticipate that by inducing specialization, trade limits the potential for convergence in energy productivity. Conversely, by inducing competition and knowledge diffusion, trade may spur sectors to greater energy productivity. Unlike most previous work on convergence, we explain productivity dynamics from cross-country interactions at a detailed sector level and apply a spatial panel data approach to explicitly account for trade-flow related spatial effects in the convergence analysis. Our study confirms the existence of convergence in manufacturing energy productivity, caused by efficiency improvements in lagging countries, while undermined by increasing international differences in sector structure. Further, we find that trade flows explain 30 to 40% of the unobserved variation in energy productivity. Trade continues to explain the unobserved variation in energy productivity even after accounting for geographic proximity. Last, we find that those countries and sectors with higher dependence on trade both have higher energy productivity growth and a higher rate of convergence, further implying that trade can enhance energy productivity. Thus, unlike concerns that trade may spur a 'race to the bottom', we find that promoting trade may help stimulate energy efficiency improvements across countries.

Abstract Awareness in Central and Eastern European countries of environmental problems is growing rapidly. Yet the social, economic, and political barriers to implementing drastic policy measures are still formidable. The acceptability of policy measures can be improved when the environmental and economic implications of alternative measures are shown in conjunction. Therefore, a prototype Computable General Equilibrium (CGE) model is constructed for Lithuania. A key question in Lithuania concerns the future use of nuclear-generated power. Using the CGE model, medium-term scenarios describing combinations of high or low economic activity, fuel prices, and nuclear potential are run for the year 2000.

Over the last decade, significant attention has been devoted to Closed-Loop Supply Chain (CLSC) design problems. As such, this review aims at assessing whether the current modelling approaches for CLSC problems can support the transition towards a Circular Economy at a supply chain level. The paper comprehensively assesses the extent to which existing modelling approaches evaluate the performance of supply chains across the complete spectrum of sustainability dimensions. Also, the capability of the current approaches of incorporating strategic, tactical, and operational decisions is considered, along with adopted solution methodologies. As a result, a comprehensive analysis was performed on 254 selected articles. This paper emphasises how most of the current literature in the field is affected by a disconnection between supply chain design and the founding principles of Circular Economy. Specifically, the CLSC literature exhibits a reductionist interpretation of the Circular Economy. CLSC studies focusing on all three dimensions of sustainability are relatively rare, and performance measurement approaches appear to be very much focused on monetary issues. While methodological contributions appear adequate to focus on the non-deterministic nature of CLSC design problems, there is paucity of empirically-grounded research. Coherently, a research agenda is proposed, in order to address the mentioned gaps and increase the relevance of this research field to practice.

Recently, in the economics literature, several papers have put forward arguments for using a declining discount rate in social-cost benefit analysis. This paper examines the impact of employing a declining discount rate on the social cost of carbon-the marginal social damage from a ton of emitted carbon. Six declining discounting schemes are implemented in the FUND 2.8 integrated assessment model, including the recent amendments to the Green Book of HM Treasury (Treasury, H.M., 2003. The Greenbook: Appraisal and Evaluation in Central Government. TSO, London). We find that using a declining schedule of discount rates increases the social cost of carbon estimate by as little as 10% or by as much as a factor of 40, depending upon the scenario selected. Although the range of plausible estimates is large, using declining discounting schemes in FUND 2.8 in most cases does not yield values at the £70/tC level suggested by UK DEFRA [Clarkson, R., Deyes, K., 2002. Estimating the social cost of carbon emissions. Government Economic Service Working Paper. HM Treasury, London]. Indeed, only at the higher end of the values of social cost of carbon found here would many climate change related policies - such as the Kyoto Protocol - pass a cost-benefit analysis. This conclusion, however, does not necessarily undermine the ethical and political economic reasons for supporting international collective action on climate change. © 2006 Elsevier Ltd.

During the last decades the production of electrical energy has been liberalized. This paper studies the effect of using a market mechanism to allocate scarce transmission capacity when the incumbent producers remain dominant. We show that granting exclusive use to an incumbent producer is preferred to trading access to this essential facility if interregional production-cost differences are significant and transmission capacity is scarce. This result counters the intuition on third degree price-discrimination, that arbitrage will improve the social surplus when there is no output contraction. The reason is that with arbitrage the incumbent can still charge different regional prices as long as it creates congestion on the transmission lines. As a consequence, welfare will be lower, since the incumbent distorts production decisions to congest the lines. We recommend that a market-oriented access to scarce transmission capacity should be accompanied by additional regulatory or structural measures to address market power.

The role of cities and their commitment to meet the European targets on energy and climate has steadily increased in the latest years as testified by the large number of ambitious initiatives undertaken by European cities to face multiple challenges towards sustainability. Many projects and initiatives have arisen all around Europe to support cities in the achievement of the Europe 2020 targets of smart, sustainable and inclusive growth. RE-SEEties "Towards resource-efficient urban communities in SEE" is one of the projects funded under the South East Europe program aimed to enhance the policy-making and strategic planning competences of municipalities in the field of energy efficiency, renewable energy sources and waste valorization. This paper focuses on the methods developed and the main results achieved in the framework of RE-SEEties. The main focus is on the eight partner cities (The Local Government of Budapest District 18 - Hungary/HU, Municipality of Aigaleo - Greece/EL, Municipality of Potenza - Italy/IT, City of Nitra - Slovakia/SK, City of Skopje - Former Yugoslav Republic of Macedonia/FYROM, City of Miercurea Ciuc - Romania/RO, Municipality of Ptuj - Slovenia/SI, City of Ivani?-Grad - Croatia/HR) and how they were assisted by professional institutions in translating their commitments towards resource efficiency into Local Strategies and Action Plans. A critical comparison of these final results points out differences and similarities in the state-of-the-art of cities across South East Europe as well as a the level of ambition and difficulties faced to turn into resource efficient urban communities.

Innovation is receiving increased attention among policymakers as a means of addressing sustainable economic development challenges. However, a range of factors such as inappropriate physical and knowledge infrastructures, incoherence of institutional frameworks, or lack of specific capabilities may have a negative impact on the functioning of the agricultural innovation system. The purpose of this paper is to apply a comprehensive innovation systems analytical framework, reconciling analyses of systemic structures, functions, failures and merits of innovation systems to assess and compare the performance of the agricultural innovation systems of Scotland and the Netherlands. To achieve this an analytical framework was drawn up based on the available literature, and through a process that included document analysis and a series of semi-structured interviews and workshops with experts in the two countries the agrifood sectors were empirically assessed. In both countries, systemic failures in terms of actors’ interactions and competencies as well as market and incentive structures were revealed. However, differences emerge between the two countries that appear to relate more to social and cultural (soft institutions) differences rather than the formal legal and regulatory frameworks (hard institutions)

Artículos en revistas The growing importance of the electricity sector in many economies, and of energy and environmental policies, requires a detailed consideration of these sectors and policies in computable general equilibrium (CGE) models, including both technological and temporal aspects. This paper presents the first attempt to our knowledge at building temporal disaggregation into a CGE model, while keeping technological detail. This contribution is coupled with some methodological improvements over existing technology-rich CGE models. The model is able to account for the indirect effects characteristic of CGE models while also mimicking the detailed behavior of the electricity operation and investment present before only in bottom-up detailed models. The present paper is the first of two parts and focuses on the bottom-up top-down calibration methodology needed to build such a model. Part II will present the CGE model applied to the evaluation of an energy policy with temporal consequences. info:eu-repo/semantics/publishedVersion
